If you're willing to tolerate a GC, Gambit Scheme may be the closest. You can learn the basics of Scheme in a short time (but any programming language will take time to master). The C FFI is also pretty straightforward to use, but developing complete Scheme interfaces to large C libraries can get tedious. Gambit is also reputed as the second fastest Scheme compiler out there; only Chez Scheme produces faster code.
